We report a case of celiac artery dissection after abdominal blunt trauma. A 29-year-old man visited the emergency room for acute left periumbilical pain after abdominal blunt trauma from his child. Computed tomography showed a wedge-shaped splenic infarction with splenic artery thrombus. He was hospitalized for careful observation, and after two days, follow-up computed tomographic angiography showed a progressed celiac artery dissection that involved common hepatic artery and an increased extent of splenic infarction. He underwent conventional angiography, and a self-expandable stent was placed between the celiac axis and the common hepatic artery. After two days, follow-up computed tomographic angiography showed good hepatic arterial blood flow via the stent and no progression of splenic infarction. After ten days, he was discharged without complications.

PURPOSE: The purposes of this study are to evaluate clinical characteristics of malnourished patients who received nutritional therapy and to compare their clinical courses according to nutritional support team (NST) consultation in tertiary referral hospital in Korea. METHODS: From June 2014 to May 2015, 43,954 admitted patients who were more than 18 years old were retrospectively investigated. Characteristics of patients who received enteral nutrition (EN) or parenteral nutrition (PN) for more than 3 days (nutritional therapy group) were compared to the patients without nutritional therapy (control group). In addition, clinical courses according to NST consultation (NST group and non-NST group) were compared through propensity score matching (PSM). RESULTS: EN or PN was applied in 4,599 patients for more than 3 days (nutritional therapy group: 10.5%). For characteristics, there were significant differences between two groups (nutritional therapy group vs. control group) with age, male proportion, body weight, body mass index. All laboratory data at admission were significantly worse in nutritional therapy group. And for clinical courses, there were significant differences in length of stay (LOS), rate of intensive care unit (ICU) admission, LOS in ICU, Acute Physiology and Chronic Health Enquiry (APACHE II) score, days of nutritional therapy, mortality rate. NST consultation was made in 39% of nutritional therapy group. Among departments, Thoracic Surgery showed the highest rate of NST consultation (68.5%) otherwise Neurosurgery showed the lowest rate (18.7%). When PSM between NST group vs. non-NST group were made, significant differences was shown only in the rate of ICU admission, EN or PN support days, cholesterol at discharge. CONCLUSION: In tertiary referral hospital in Korea, more than 10% of patients still needed active nutritional therapy. NST consultation rate varies among departments. We failed to find significant differences between NST group and non-NST group.

Near-infrared (NIR) fluorescence imaging is a promising method for image-guided surgery, providing robust functional images with relatively good cost-effectiveness. A cyanine vital dye indocyanine green (ICG) is a safe NIR fluorophore emitting 800~840 nm of light and has been used in numerous surgical procedures. The technique has been applied to lymph node navigation of gastric cancer surgery with an expectation of better visualization of lymphatic structures without any risk of radio-hazard compared with a “dual method” using both vital dyes and radioisotopes. Given the characteristics of ICG, such as fast distribution and quenching effect, diluted concentrations, such as 0.05~0.1 mg/ml, are thought to be optimal for sentinel node navigation. Injection into the subserosal layer is feasible; however, endoscopic submucosal injection has advantages of improved accuracy of the injection site and feasibility of injection one day prior to surgery; these advantages are preferred by some investigators due to a smaller number of sentinel nodes compared with injection in the operation theatre. The technology requires evaluation of the sensitivity and specificity, as well as the non-inferiority, compared with the dual method in a large cohort for justification as a safe node navigation method.

PURPOSE: The European Organization for Research and Treatment of Cancer quality-of-life questionnaire-OG25 was developed to evaluate the quality of life in patients with stomach and esophageal cancer. The following are included in the OG25 but not in the STO22: odynophagia, choked when swallowing, weight loss, trouble eating with others, trouble swallowing saliva, trouble talking, and trouble with coughing. In this study, we evaluated the quality of life of gastrectomized patients using both, the OG25 and the STO22. MATERIALS AND METHODS: A total of 138 patients with partial gastrectomy (PG) (distal gastrectomy=91; pylorus-preserving gastrectomy= 47) and 44 patients with total gastrectomy (TG) were prospectively evaluated. Body weight and scores from the OG25 and STO22 were evaluated preoperatively and at 3 weeks, 3 months, and 6 months after surgery. RESULTS: Patients with TG had significant weight loss compared to patients with PG. At 3 months, TG was associated with worse scores for dysphagia, eating, odynophagia, trouble eating with others, trouble with taste, and weight loss on the OG25. TG was also associated with dysphagia, eating restrictions, and anxiety on the STO22. The OG25 helped differentiate between the groups with respect to weight loss, odynophagia, choked when swallowing, and trouble eating with others. The OG25 scores changed over time and were significantly different. CONCLUSIONS: The OG25 is a more sensitive and useful scale than the STO22 for evaluating the quality of life of gastrectomized patients, especially those with total gastrectomy.

PURPOSE: The utility of 18-fluordesoxyglucose positron emission tomography ([¹⁸F]-FDG-PET) combined with computer tomography or magnetic resonance imaging (MRI) in gastric cancer remains controversial and a rationale for patient selection is desired. This study aims to establish a preclinical patient-derived xenograft (PDX) based [¹⁸F]-FDG-PET/MRI protocol for gastric cancer and compare different PDX models regarding tumor growth and FDG uptake. MATERIALS AND METHODS: Female BALB/c nuu mice were implanted orthotopically and subcutaneously with gastric cancer PDX. [¹⁸F]-FDG-PET/MRI scanning protocol evaluation included different tumor sizes, FDG doses, scanning intervals, and organ-specific uptake. FDG avidity of similar PDX cases were compared between ortho- and heterotopic tumor implantation methods. Microscopic and immunohistochemical investigations were performed to confirm tumor growth and correlate the glycolysis markers glucose transporter 1 (GLUT1) and hexokinase 2 (HK2) with FDG uptake. RESULTS: Organ-specific uptake analysis showed specific FDG avidity of the tumor tissue. Standard scanning protocol was determined to include 150 μCi FDG injection dose and scanning after one hour. Comparison of heterotopic and orthotopic implanted mice revealed a long growth interval for orthotopic models with a high uptake in similar PDX tissues. The H-score of GLUT1 and HK2 expression in tumor cells correlated with the measured maximal standardized uptake value values (GLUT1: Pearson r=0.743, P=0.009; HK2: Pearson r=0.605, P=0.049). CONCLUSIONS This preclinical gastric cancer PDX based [¹⁸F]-FDG-PET/MRI protocol reveals tumor specific FDG uptake and shows correlation to glucose metabolic proteins. Our findings provide a PET/MRI PDX model that can be applicable for translational gastric cancer research.

PURPOSE: This study aimed to evaluate the value of serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels to detect gastric cancer recurrence. MATERIALS AND METHODS: We retrospectively reviewed 154 patients who developed recurrence within 2 years after curative gastric cancer surgery and analyzed the relationship between postoperative CEA and CA19-9 levels and recurrence. We readjusted the cut-off values to improve the detection of recurrence. Subgroup analysis according to clinicopathologic variables was performed to further investigate the relationship between recurrence and CEA and CA19-9 levels. RESULTS: The sensitivity and specificity for elevated CEA levels to detect recurrence were 40.6% and 89.5%, respectively, and those for CA19-9 were 34.2% and 93.6%, respectively. The sensitivity and specificity for elevation of either tumor marker were 54.3% and 84.0%, respectively; those for elevation of both tumor markers were 19.2% and 98.4%, respectively. By readjusting the cut-off values from 5.0 ng/ml to 5.2 ng/ml for CEA and from 37.00 U/ml to 30.0 U/ml for CA19-9, the sensitivity was increased from 34.2% to 40.2% for CA19-9, while there was no increase in sensitivity for CEA. In subgroup analysis, the sensitivity of CEA was higher in patients with elevated preoperative CEA levels than in patients with normal preoperative CEA levels (86.7% versus 33.7%; P<0.001). Furthermore, the sensitivity of CA19-9 was higher in patients with elevated preoperative CA19-9 levels than in patients with normal preoperative CA19-9 levels (82.61% versus 26.83%; P<0.001). CONCLUSIONS: CEA and/or CA19-9 measurement with the readjusted cut-off values allows for more effective detection of gastric cancer recurrence.

PURPOSE: The effectiveness of enteral nutrition for patients with anastomotic leakage after gastric cancer surgery is controversial. The purpose of this study is to compare effectiveness between combined enteral nutrition with parenteral nutrition (EPN) and total parenteral nutrition (TPN). METHODS: Patients who underwent gastric cancer surgery for primary gastric cancer from April 2010 to August 2012 were reviewed. Clinicopathologic characteristics, complication, laboratory tests, and body weight (Bwt) were compared between EPN and PN. RESULTS: Among patients with postoperative leakage within postoperative 1 month (n=43), 13 patients were supported by EPN and 23 patients by TPN. Clinicopathologic characteristics, including preoperative Bwt, body mass index, nutritional status, other complications, and TNM stage were similar. Preoperative serum albumin and Bwt were similar between EPN and TPN. However, after 1 week of nutritional support, albumin at EPN was significantly higher than that of PN (3.52+/-0.3 and 3.25+/-0.3; P=0.010). Adjusted by preoperative Bwt, preoperative nutritional status, and difference in Bwt between preoperative and pre-nutritional support period, decrease of Bwt between pre-nutritional support and discharge was significantly less at EPN than at TPN (-4.5+/-5.4% and -6.3+/-4.1%; P=0.001). CONCLUSION: In terms of the maintenance of serum albumin and Bwt during nutritional support, EPN may be a better supportive option than TPN for patients with anastomotic leakage after gastric cancer surgery.

PURPOSE: The purpose of this study is to investigate differentially expressed genes using DNA microarray between advanced gastric cancer (AGC) with aggressive lymph node (LN) metastasis and that with a more advanced tumor stage but without LN metastasis. MATERIALS AND METHODS: Five sample pairs of gastric cancer tissue and normal gastric mucosa were taken from three patients with T3N3 stage (highN) and two with T4N0 stage (lowN). Data from triplicate DNA microarray experiments were analyzed, and candidate genes were identified using a volcano plot that showed > or = 2-fold differential expression and were significant by Welch's t test (p < 0.05) between highN and lowN. Those selected genes were validated independently by reverse-transcriptase-polymerase chain reaction (RT-PCR) using five AGC patients, and tissue-microarray (TMA) comprising 47 AGC patients. RESULTS: CFTR, LAMC2, SERPINE2, F2R, MMP7, FN1, TIMP1, plasminogen activator inhibitor-1 (PAI-1), ITGB8, SDS, and TMPRSS4 were commonly up-regulated over 2-fold in highN. REG3A, CD24, ITLN1, and WBP5 were commonly down-regulated over 2-fold in lowN. Among these genes, overexpression of PAI-1 was validated by RT-PCR, and TMA showed 16.7% (7/42) PAI-1 expression in T3N3, but none (0/5) in T4N0 (p=0.393). CONCLUSION: DNA microarray analysis and validation by RT-PCR and TMA showed that overexpression of PAI-1 is related to aggressive LN metastasis in AGC.

We report our experience with two cases of situs inversus totalis, both involving patients diagnosed with gastric cancer. These were a 52-year-old male with a preoperative staging of cT1bN0M0 and a 68-year-old male with a staging of cT2N0M0, both of whom underwent surgery. The former was found to have vascular anomalies in the preoperative computed tomography, so we performed a computed tomography angiography with three-dimensional reconstruction. Laparoscopy-assisted distal gastrectomy with Billroth I anastomosis was performed with D1+ lymph node dissection, and a small laparotomy was made for extracorporeal anastomosis. In contrast, the latter case showed no vascular anomalies in the preoperative computed tomography, and totally laparoscopic distal gastrectomy with delta anastomosis was performed with D1+ lymph node dissection. There were no intraoperative problems in either patient and they were discharged without postoperative complications. Histopathological examination revealed a poorly differentiated adenocarcinoma (pT2N0M0) and a well-differentiated adenocarcinoma (pT1aN0M0), respectively.

Given the rapid growth of the population of cancer survivors, increased attention has been paid to their health problems. Although gastric cancer is one of the most common cancers, empirical evidence of survivorship care is limited. The objectives of this study were to describe the health care status of gastric cancer survivors and to report the experience of using the shared-care model during a one-year experience at the cancer survivorship clinic in Seoul National University Hospital. This is a descriptive, single-center study of 250 long-term gastric cancer survivors who were referred to the survivorship clinic. The status of their health behaviors, comorbid conditions, secondary cancer screenings, and survivorship care status were investigated through questionnaires and examining the medical records. Among the survivors, 7.2% were current smokers, 8.8% were at-risk drinkers, and 32.4% were physically inactive. Among the patients who did not know their bone density status, the majority were in the osteopenic (37.1%) or osteoporotic range (24.1%). Screening among the eligible population within the recommended time intervals were 76.3% for colorectal cancer, but only 13.6% for lung cancer. All of the survivors were provided with counseling and medical management at the survivorship clinic, as appropriate. In conclusion, Long-term gastric cancer survivors have various unmet needs. Shared-care through survivorship clinics can be an effective solution for providing comprehensive care to cancer survivors.
